Function Documentation

int meshes_2D_sph_create	(	int	verbose,
		SphTriangle *	t
	)

Perform the spherical triangulation

Returns

Error return code

Parameters

[in]	verbose	Verbose option
[in]	t	SphTriangle structure

void meshes_2D_sph_free	(	SphTriangle *	t,
		int	mode
	)

Free the structure for triangles on a sphere

Parameters

[in]	t	Pointer to the SphTriangle structure to be freed
[in]	mode	1 for partial deallocation 0 for total deallocation

int meshes_2D_sph_from_auxiliary	(	const String &	triswitch,
		SphTriangle *	t
	)

Add auxiliary random points

Parameters

[in]	triswitch	Triangulation option
[in]	t	SphTriangle structure

Remarks

This function adds the vertices to an existing SphTriangle structure

int meshes_2D_sph_from_db	(	Db *	db,
		SphTriangle *	t
	)

Define the memory areas by reading information from Db

Parameters

[in]	db	Db structure where data are located
[in]	t	Pointer to the SphTriangle structure to be loaded

Remarks

This function adds vertices to an existing SphTriangle structure

A conversion is launched to convert the 2-D information

(longitude,latitude) into 3-D coordinates

int meshes_2D_sph_from_points	(	int	nech,
		double *	x,
		double *	y,
		SphTriangle *	t
	)

Add fixed points to modify the SphTriangle structure

Parameters

[in]	nech	Number of added samples
[in]	x,y	Array containing the coordinates of added points
[in]	t	Pointer to the SphTriangle structure to be loaded

Remarks

This function adds the vertices to an existing

SphTriangle structure

void meshes_2D_sph_init

(

SphTriangle *

t

)

void meshes_2D_sph_print	(	SphTriangle *	t,
		int	brief
	)

Print the contents of the SphTriangle structure

Parameters

[in]	t	Pointer to the SphTriangle structure to be printed
[in]	brief	1 for a brief output; 0 otherwise
